Abstract: 1,209,844. X-ray diffraction apparatus. ELECTRICITE DE FRANCE (SERVICE NATIONAL). Feb. 6, 1968 [Feb.17, 1967], No.5784/68. Heading G1A. [Also in Division H5] An automatic goniometer used in studies utilizing small angle X-ray diffraction comprises a pivoting arm 3 Fig. 1 a radiation detector 7 carried by the arm, a counting system associated with the detector, a fixed sample carrier 20 centred on the axis of rotation 15 of the arm, means for pivoting the arm comprising micrometer screw 21 driven by a step by step motor 32 Fig.2 the end of said screw acting on a bearing member 23 of arcuate form, the centre O of the arc being on the longitudinal axis of the arm 3 the member 23 being fixed to one side of the arm by a rod which is on a radius of the arc and substantially perpendicular to the longitudinal axis, the arm being pivoted automatically by an electronic circuit in a series of steps, a series of counts being accomplished at each step. The motor 32 is preferably started by a pulse formed in the electronic circuit which closes its supply circuit and is stopped by means of a cam e.g. 34 which actuates a micro-switch 33 to open the circuit. The distance between the axis 15 and the arc centre O is preferably such that the rotation of the arm 3 by an exact decimal fraction of a degree corresponds to an advance of one revolution of the screw 21. The fluctuations with time of the incident X-ray beam from tube 8 are compensated for by adjusting the duration of e.g. count e.g. by means of a monitor detector 11 which functions with a constant number of counts, the stopping of the monitor count functioning to stop the count of the main detector 7. The angular position of the arm is monitored by means of cam 38 and micro-switch 37 which is arranged to deliver a pulse to a counting system just before the stopping of the motor 32. The same counting system also registers the pulses for starting the motor 32 and is arranged to deliver an alarm signal when a starting pulse is not followed by a stopping pulse.

Title: Gating Circuit and Magnetic Store Incorporating the Gating Circuit
Inventor: COMMANDER ROBERT DUNCAN
IPC: G11B15/087
Filed: 1969-02-05
Abstract: 1,193,804. Pulse discriminating circuits. INTERNATIONAL BUSINESS MACHINES CORP. 5 Feb., 1969, No. 6115/69. Heading H3T. [Also in Division G4] A pulse selecting circuit comprises an input gate receiving the input pulse train, a sawtooth generator having a fixed amplitude flyback and which opens the gate when the ramp exceeds a given level, the generator being triggered by the output from the gate, a further gate receiving the output of the first and being enabled by the ramp generator when the flyback does not pass a given threshold level due to the spacing between the triggering pulses and thus the amplitude of the ramp exceeding a given value. The invention is applied to a train of pulses from a magnetic storage disc, data being represented by pulses D1, Fig. 4a preceded by a clock pulse C and the address by pulses 54, 55 not preceded by a clock pulse. The input circuit comprises a combination of gate 14 and a flyback and ramp generator having a fixed amplitude flyback, described in Specification 1,126,160 and with reference to Fig. 2 (not shown). Briefly, the ramp generator produces an output 4b which, following a clock pulse, provides a gating pulse 4c lasting until the ramp reaches a valve L, the pulse closing gate 14 long enough to block the next data pulse so that only clock pulses and address pulses (i.e. pulses not preceded by a clock pulse) are selected by gate 14, the output of the gate being used to trigger the flyback. The circuit also selects at 15 (Fig. 2) the data pulses. The gating pulses 4c and the selected clock and address pulses from 14 are applied to an AND gate 59 to produce pulses 4d coincident with clock and address pulses. Gates 60 and 63 are crosscoupled to form a bi-stable circuit. It is set by pulses from 14 and reset when the flyback passes threshold L, to produce pulses 4(e). Thus it remains reset during the absence of clock pulses. Gates 68 and 70 also form a bistable circuit. It is controlled by 4e and by the output of an AND gate 66 itself controlled by 4e and the output of gate 14 so as to produce narrow pulses concident with clock pulses and pulses starting at the second address pulse and ending at the next clock pulse 4h. These pulses control a gate 72 which also receives the output of a gate 14 so as to produce pulses coincident with the second address pulse and the next clock pulse (4k). In order to prevent zero drift and pulse timing errors, shown dotted in 4(b), from causing false switching of bi-stable circuit 60, 63, a monostable circuit 74 produces inhibit pulses during this period. The second bi-stable circuit may be replaced by a timing circuit.

Title: Improvements in and relating to the feeding of tobacco for cigarette making machines
IPC: A24C5/39
Filed: 1944-04-06
Abstract: 575,806. Feeding tobacco to cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. April 6, 1944, No. 6497. Convention date, Feb. 19, 1943. [Class 130] Tobacco for cigarettes is subjected to a continuous feeding movement through a restricted curved passageway and repeated additional and more rapid feeding movements, in the direction of the continuous movement, are superimposed thereon to compact the tobacco. Tobacco removed from a carding roller 11 by a picker 25 is showered on to the upper part of a plate 30 by a fan 26 and slides down the plate to a feed roller 32 which forwards it into a passage P between a concave 34 and a roll 36 adapted to compact and feed forward the tobacco. The roll 36 is mounted on an eccentric portion 112 of a shaft 109 to produce an oscillating movement towards and away from the concave 34, the shaft 109 being rotated rapidly and the roll 36, which is independently driven, being mounted on the eccentric part 112 of the shaft 109 through a rubber annulus 128 which absorbs the eccentric movements between the roll and its driving gear 128. The compacted tobacco stream is directed around a more slowly moving roller 38 by a concave 40 before being showered on to the cigarette paper or a conveyer 44 by a picker 42. To prevent any tobacco being lost as it leaves the compacting roll 36, a guide or doctor blade 142 directs it into the concave 40, the blade being resiliently mounted to allow for the eccentric movement of the roll 36. The roll itself is provided with a flange 119, Fig. 5, concentric with the eccentric shaft 112 and a rubber buffer between the flange 119 and a flange 124 connected to the non-eccentric part 113 of the shaft 109 transmits the drive to the roller.
